Abstract

NEW MATERIAL:An oligosaccharide which is expressed by the formula and consists of O-α-D-glucopyranosyl-(1→3)-O-α-D-glucopyranosyl-(1→4)-O-α-D-glucopyranosyl-(1→4)-D-glucose, and has the following physicochemical properties. Elementary analysis: C, 43.24 (43.18)%; H, 6.36 (6.41)% (values in the parentheses are the theoretical ones). Molecular weight: 66.7. The polymerization degree of glucose: 4. Melting point: Immeasurable due to the difficult crystallization. [α]D25 +185° (c=1.0, water). Readily soluble in water, slightly soluble in ethanol, etc.; insoluble in ether, etc. Positive to the anthrone reaction, etc. Positive to the anthrone reaction, etc.
USE: Useful as a substrate for determination of α-1,3-glucosidase, a fermentation culture medium, an enzyme derivative, etc.
PROCESS: Elsinan is hydrolyzed with an α-amylase in the presence of an acetate buffer solution at 45°C for 24hr to give the titled oligosaccharide.
